I've tried to read a piece of my trace file, but there was a lot of constant tags like (0x0300000D) and (0x0300000B) and I could not find these at http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r0m0/topic/com.ibm.etools.mft.doc/as08560_.htm

Does anyone know where to find more informations about?

Fair question...

Remember that each WMB parser uses the ls 3 bytes of the Type field in a different way. The top byte (4th byte) s consistently used to indicate Name / Value / NameValue. For the MRM parser, in current releases the ls byte is interpreted as follows ( and bytes 2 and 3 are not used ).

bit 0 : syntax element was created by an MRM parser
bit 1 : element/attr was successfully matched with message definition
bit 2 : element/attr was not matched with message definition ( so is self-defining )
bits 3..5 : Type of node
--001--- : Field
--010--- : Structure
--011--- : Message
--100--- : Root ( i.e. the node with name 'MRM' )

Note that these are internal values ( the MRM parser does not expose them as ESQL constants) , so they might be subject to change in future.
